Differential diagnosis. The new species is related to Neopronematus sepasgosariani Sadeghi, Łaniecka and Kaźmierski, 2012 . These two species have the relatively long and serrate dorsal body setae, bifurcate setae ag3 and similar ornamentation. The features differentiating both species are provided in Table 6 and refer to females.

The new species also resembles Neopronematus neglectus (Kuznetzov, 1972) in general appearance. However, N. neglectus has significantly shorter setae (Kuznetzov 1972b).

N. sepasgosariani Sadeghi, Łaniecka and Kaźmierski N. solani sp. nov.

Distances: c1–c1 36, d1–d1: 34, e1– e1 41, f1–f1 21, h1–h1 14, f1–h1 21. Lyrifissures ia situated more or less half distance between setae c1 and d1 and slightly laterally to imaginary line c1–d1. Lyrifissures im —anterior to and closely associated with setae e1. Lyrifissures ip situated approximately half distance between e1 anf f2, slightly laterally to imaginary line e1–f2. Lyrifissures ih latero-ventrally, anterior to and closely associated with ps1. Venter striated. Striae longitudinal between metasternal setae. All ventral setae similar in shape to dorsal setae (with exception of ag3, see below), but much shorter (8–12). Genital opening in shape of inverted “T”. 4 pairs of agenital setae. Setae ag1 (10), ag2 (10) and ag4 (13) spindle-like, ag3 are bifurcate (6). No genital and eugenital setae. Pseudanal valves folded, with 1 pair of setae (ps3). Epimeral formula: (3-1-4-2). Gnathosoma. Visible from above. Palps eupathidium (pζ) straight and forked distally, 4 long. Cheliceral stilettos (16) longer than palpal tarsus (13/5). Palpal femuro-genu: length 20, width 11. Palpal setation (5+ ω -1-2). Legs. Setation: I (8+ ω -3+ k+φ -3-3-1), II (6+ ω -2-3-3-1), III (5-2-2-2 –1), IV (5-2-1-2-0). Femur IV not divided. Tarsus I without apotele, with 3 pairs of long setae (fastigials, tectals and prorals) and 1 pair of undersized unguinals (u), based ventrally and close to prorals. Measurements: tarsus I length/width: 24/14 (proportion index 1.7), seta ft’ 23, ft’’ζ 31, tc’ζ 36, tc’’ζ 35, p’ζ 18, p’’ζ 24, (u) 2.25. Solenidion ωI 8/1, 3 times shorter than tarsus. Tibia I 19/15, famulus k’’ 3 (“Y”-shaped), solenidion φ 4. Solenidion ωII on tarsus II oval in outline, small (3 long). Tarsi II–IV each with apotele, 2 claws and ciliated empodium, but without empodial claws (om).

MALE (paratype). Idiosoma: length 160, width 96 (proportion index 1.7). Other males (3): 155– 160/95–100. Most of characters same with exception of following: solenidion ωI extremely long (nearly 25), relatively thick (nearly 2 in its broadest part) and strongly bent. Femora IV distally with strong, bent and pointed spur. Single pair of rounded, dorsal opisthosomal discs present between setae d1 and e1, slightly laterally to d1–e1. These discs covered by chess-shaped pattern looking like sieves. Diameter of discs about 12.

Remark. The male dorsal opisthosomal discs have been never observed before.
